The Clearblue Pregnancy Test with Weeks Indicator is the first and only test as accurate as an ultrasound in dating pregnancy1. Your Smart Dual Sensor™ tells you if you are "Pregnant" or "Not Pregnant" and for how long.
There are two tests in one. First, it detects the presence of the pregnancy hormone with an accuracy greater than 99% from the expected day of menstruation and ALSO indicates how many weeks ago you became pregnant, 1-2, 2-3 or more than 3 weeks ago (+3). The Weeks Indicator is 93% accurate in detecting the date of conception.
The test is so sensitive that it can test up to 5 days before your expected period.
Within 3 minutes, the "Pregnant" or "Not Pregnant" result appears on the display. If the result is "Pregnant", the test also indicates how long ago you became pregnant (1-2, 2-3 or +3 weeks).
